in another animal (of the equine or human spe- 

 cies), and which discharge is sooner or later 

 accompanied by vascular injection and chancrous 

 ulceration of the schneiderian membrane, by 

 tumefaction of the submaxillary lymphatic glands, 

 and by farcy. — Percival. 



Symptoms. — A discharge of matter from one 

 or both nostrils, enlargement of one or both sub- 

 maxillary glands. When one nostril only is 

 affected, the corresponding gland is almost inva-

 thick, but oftener of a grayish aspect. A dis- 

 charge from the nostrils, and the appearance 

 of ulceration, is not alone suflSfient to establish 

 the presence of the disease ; for these ulcerations 

 are sometimes produced by the acrid nature 

 of the discharge from catarrh. In the first stage 

 of the disease, there is a discharge from one 

 nostril only of a whitish humor, which is incon- 

 siderable, except when the horse has been exercised 

 for some time. There is an increased redness 

 of the membrane within the nostrils. The swell-

 side as the affected nostril. The horse's coat 

 appears healthy, and the animal in good condition.

 from those of glanders produced by bad proven-
